I know you're jesting, but in case someone else misunderstands, even if every person is 100% efficient and rational for real, the market is still chaotic and unpredictable. Like the weather system, every molecule of air and water behaves "deterministically". And yet, we can predict no more than a few days, may be a few weeks at most, with any real accuracy. This is the hallmark of a chaotic system (aka the error in prediction grows exponentially).
